The following applies to pneumatic diagram
V300420 and V300421:
NOTE:
The mechanical position of the splitter
switch engaging cylinder (Low (L) and High
(H)) depends on the gearbox version: direct
drive or overdrive.
The gear lever (5) has two switches, one for the
splitter group (GV) and one for the range group
(GP). Both switches are ventilated through
connection 1 of the gearbox lever (5).
During a splitter switch, connection point 22 and
connection point 41 of the splitter relay valve (8)
are ventilated. As a result, the splitter relay valve
will be pushed into the low (L) position. When
the clutch pedal is fully depressed, the splitter
relay valve will be connected to the air supply
via connection 2 of the GV valve (7).
The splitter cylinder (8) is switched to the low (L)
position.
If the GV switch (5) is then returned to the high
(H) position, connection 41 of the splitter relay
valve (8) will be bled via connection point 22 of
the gear lever (5). As a result of the
disappearance of the air pressure at connection
41, the splitter relay valve will move to the high
(H) position. When the clutch is operated, the
GV valve (7) will again connect the air supply to
connection point 1 of the splitter relay valve (8).
This causes the splitter cylinder to move to the
low (L) position.
The rear-mounted range box (range group) is
operated via the GP switch (5). When
the GP switch (5) is operated, the air supply will
be connected to connection point 4 of the
electropneumatic valve (6) of the downshift
protection.
